Problems solved by technology

However, due to the large flow resistance and low flow rate of the PTC circuit, the cold start of the fuel cell is slow, or the cold start fails due to the huge temperature difference from the inlet to the outlet of the fuel cell.

Abstract

The invention discloses a passenger car fuel cell thermal management system and method. The thermal management system includes a controller, a fuel cell, an inlet temperature sensor, an outlet temperature sensor, a PTC heater, a warm air core, a first water pump, Electric control three-way valve, deionizer, radiator, second water pump and intercooler; the heat management method includes the heat management process in the shutdown mode of the fuel cell, the heat management process in the cold start mode, and the low power operation The thermal management process in the mode and the thermal management process in the high-power working mode. The invention can make the fuel cell start quickly and avoid the failure of the fuel cell cold start.

Description

technical field [0001] The invention belongs to the field of hydrogen fuel cell vehicles, and in particular relates to a fuel cell thermal management system and method for passenger vehicles. Background technique [0002] A fuel cell passenger vehicle is a passenger vehicle in which the fuel cell consumes reactants to generate electric energy as all or part of the power source to drive the vehicle forward. In recent years, due to environmental and energy issues, coupled with the advantages of fuel cells such as high power and no pollution, fuel cell passenger vehicles have a good application prospect. [0003] Proton exchange membrane fuel cells work best at a temperature of about 80 degrees Celsius, and it is very important to ensure a reasonable operating temperature for fuel cells. Traditional engine heat dissipation mainly dissipates in the form of exhaust gas through the engine body and exhaust pipe, and only a small amount of heat is dissipated through the radiator. U...
